The goal of technology assessment (TA) is to lend support to society and policy making by promoting understanding of the problems related to the grand sociotechnical challenges of our time, as well as to assess the available options for managing them. Researchers from Japan and Europe reflected together in this book on country-specific developments to identify the conditions that must be present to anchor TA in science, politics, and society. This book helps us to learn about different cultures.

The paper aims to understand the degree of transition towards e-mobility. The assumption is that the degree of convergence between actors of each system (batteries, vehicles, grid, policies, business models and consumers) is an indicator of changes in the present socio-technical regime. After an introduction to the socio-technical transition towards e-mobility, the paper presents and discusses three technology assessment approaches to several projects related to technology, society and politics. There are several thematic crossovers between all projects presented leading to a synergetic technology assessment. This output results from the overlapping areas between the cases and can be used to first assess the extent of changes in the present socio-technical regime, as well as to extract standards and regulations, acceptance/risk analyses and behaviour changes that could be significant in the context of a transition towards electric mobility.

Future Oriented Technology Analysis (FTA) has been visible in railway planning since 2001. Over a dozen reports have been produced in the past thirteen years, the majority being descriptive endogenous technocentric visions. They have played a role in the revitalization of the sector, predominantly relating to collective alignments and interdependencies in choice and form of the technological path the various stakeholders’ follow to achieve policy goals. A striking example is the case of ERRAC visions, where strategic agendas and roadmaps greatly impacted the high-speed train technology transition from the second to the third generation of vehicles. However, today’s socio-economic events have revealed the limitations of previously applied FTA fall short for railways. In particular, there is an inability to bridge technocentric visions with the societal challenges that are becoming increasingly prominent on the policy agenda. To fill this FTA-need in railways it is here proposed a role for constructive technology assessment as bridging function towards achieving success in the transition to a next generation of high-speed trains. The findings here presented result from the analysis of reports and interviews with their commissioning institutions and drafters.
